Today, students were called to the task of determining the last meal a murder victim ate. They were provided with the "stomach contents" of the murder victim, and performed tests to determine whether the victim had eaten protein, carbohydrates, lipids, or sugars. They then decided whether the victim last ate at Pudgie's Pizza, Gino's Italian Restaurante, or Buffalo Wild Wings, based on the tests they performed. Enjoy the pictures below!
All the materials: The "stomach contents" in the beakers, Iodine Reagent (for starch test), Biuret Reagent (for protein test), Benedict's Solution (for glucose test), and brown paper bags (for lipid test)
Mike, a little grossed out by the smell of the "vomit!"
Jenna adding Biuret reagent to test for proteins
Beth and Justin performing protein test
Dylan and Bryan putting their test tube in the hot bath
Test tubes in the hot bath to see the vomit reacts with Benedict's solution, which would show the presence of glucose
All the test results from left to right: Negative test for protein, negative test for glucose, positive test for starch, and positive test for lipids (stain left on brown bag)
